| Abstract |
Single-switch dc-dc converters and inverters for motor drives can be analyzed in a unified manner by
identifying the fundamental building block used in their implementation. The fundamental building
block can be represented as a two-port network by using cycle-by-cycle averaging (CCA) technique.
Such a representation enables the analysis of switching converters using classical tools such as
frequency domain methods. This approach, well suited for the first course on Power Electronics,
clearly illustrates the objective of the pulse-width-modulated (PWM) switching process in
synthesizing the output in switch-mode converters. Further, the use of an averaged representation of
the switching process helps speed-up dynamical simulations in circuit simulators like PSpice. This
paper describes the CCA technique and representation of converters using CCA model of switching
elements. |
